Overview
The ZF 5838.052.005 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This part serves as the primary structural carrier for the differential and wheel-end gearing, transferring torque from the transmission to the wheels under extreme load conditions. As a genuine ZF part, the SKU 5838.052.005 ensures precise fitment and metallurgical integrity required for sustained off-road operation. It integrates directly with the axle housing to support the 5838109006: DIFFERENTIAL and the 2095209037: DIFFERENTIAL assembly, forming the backbone of the drivetrain’s load-bearing architecture.
Symptoms of Failure
When the ZF 5838.052.005 REAR AXLE begins to fail, operators typically notice these specific warning signs:
- Persistent oil seepage at axle flange seals – Cracks or warping in the axle beam allow lubricant to escape, leading to low differential oil levels and eventual gear damage.
- Abnormal driveline vibration under load – A worn or bent rear axle causes uneven rotation, producing a rhythmic shudder during acceleration or when climbing grades.
- Metallic grinding from the rear housing – Internal fatigue fractures in the axle shaft or spline wear create audible contact with the 2095309059: DIFF.HOUSING, indicating imminent structural failure.
- Uneven tire wear patterns – A misaligned rear axle alters wheel tracking, accelerating tread degradation on one side of the machine.

Compatibility
This rear axle is designed for integration with ZF’s heavy-duty transmission series commonly deployed in wheel loaders, graders, and dump trucks. It is a direct fit for the ZF WG180 and ZF WG200 power shift transmissions, as well as the ZF 4WG-200 series. The part also interfaces with the 0750117075: TAPER ROLLER BEARING for proper axial load management. For complete assembly, verify compatibility with your specific axle housing casting number before installation.
